About this book
Fortress Sol (2024, 384 pages) follows Creation Node in Stephen Baxter's recent run of cosmic-scale standalones, and is one of the two later entries -- alongside Hearthspace -- built around a far-future humanity confronting an ancient alien threat. Whether this run constitutes a formally titled trilogy remains unconfirmed, so it's tracked here as a sequential standalone.
